When he starts stuffing himself with the nachos the table is red and the litter is gone. When the crew prevent him from eating nachos and 'going to the bathroom' at the same time, the bar is a wide open space with no tables at all.
Continuity mistake: When Gunter is trying to figure out where the hat goes, the banana disappears and reappears between shots.

The Honking - S3-E1
Revealing mistake: In the final battle, Bender has fry trapped into the seat inside of him, and he drives over a ramp and nearly smashes into the original were-car mid-air. But when the were-car lands on the same ramp that Bender took off from, we see that the furnace is literally touching the end of the ramp. How did Bender get up enough speed to launch himself into the air, especially accidentally (he would have had to turn 90 degrees to get onto the ramp) with the furnace that close? Also at the start of this scene, we see the were-car crying in front of the furnace, and the ramp is nowhere to be seen. (00:19:50)

How Hermes Requisitioned His Groove Back - S2-E14
Continuity mistake: When Hermes said that the form that Morgan filled out for a "regulation date that ended in regulation disappointment" was stamped only four times. The form shows three red stamp marks close to each other and a fourth one at the bottom right corner of the page by itself. Hermes then puts the form on 1.0s' desk and the first red stamp in the upper left corner is now by itself and the second and third stamp marks are now next to the fourth stamp mark. When we get a close-up of 1.0 looking at the form the stamp marks are back in their original place. (00:20:10)
Continuity mistake: When Bender is a "female" and is putting stuff in his locker, in one angle you can see a yellow item next to his pink handbag. Then in the wider angle, this item is gray.

Answer: Yes Leela knew from early on that Fry had feelings for her. They were pretending to be a couple in 'A Flight to Remember' from season 1 and Fry tried to get on dates with Leela ever since. She just didn't show signs of the feelings maybe being mutual before some of the later episodes.
